DEVICE FOR GRINDING COOKED VEGETABLES.

Application filed May 12,

The invention relates to a device used for grinding cooked vegetables to a. pulp very quickly7 and the object is, lirst, to replace the present dii'licult and wasteful inethod of forcing the cooked i'rood through an ordinary wire strainer with a Spoon, a custom now generally prevailing in preparing; foods for babies during` the early feeding months; and, second, to provide a siinple and quickly operated utensil for housewives to reduce cooked vegetables to a fine pulp for use in gravies, sauces and the like.

In the drawingl which accompanies this application, Fig'. 1 is a side view of the device in the closed position; Fig. 2 is a plan view ae eeen troni the top, also in the closed position; and, Figi'. 3 is a view of the device iii perspective showing' the handles partly separated, illustrating the relationship of the grinding* element and crank to the other parts. A. sinall pai-t of the surface oi the grinder has heen illustrated as cut away in the upper right hand corner in order to show the inethod of Securing the Wire inesh to the convex surface of the grinder as explained in detail in a later paragraph.

i The device consiste oic an aluminum casting, l, which is cast in the forni oil a ring" with handle attached. Into the ringv portion of the casting; is inserted a Wire inesh strainer, 2, in the manner shown in Fig. 1, and riveted ae at 3, for security. This combination is called the receptacle.

[in aluiiiinuiii casting, t, is fastened to Athe receptacle as at 5, hjvineana ot a hole drilled through both castings and a. pin ineerted, in the manner shown in Fig'. 3; such clearance being allowed so as to ghierniit oil ease of motion between the two castings. hearing, 7, is provided in the iniddle oi the casting, 4i, for the purpose o supporting; the shaft oilI the crank, 8, which ie permanently attached to the grindingeleinent, 2, and is intended to rotate saine. ing element, 9, heretofore referred to, consiste The lrrind- 1927. Serial No. 190,816.

of Sheet aluininuin spun to the forni of a half hall, forming` a convex suriiace on one side and acoiicave slirl'ace on the other side. vWire inesh, l0, sin'ular 'to that used in the `construction oil the strainer, 2, is stretched tightly, and completely covering the convex eurn 1 t n race of the said hali hall torni; is then '.tolded over the edge oli the I'orni toward the concave Side of the forni and held in position hy ineans o' a collar, 11, which is torcer downward on the inside of the halt` hall, in the manner shown in the cut out section ot the grinding element, 9, in Fig. 3. The collar, 11, is a, forced lit but also riveted as at 12 and 13 for lgreater security.

The device is operated by maintaini'np` pressure on both handles With one hand and turning` the crank, which operates the convex grindingksurface, With the other hand.

I ani aware that grinding machines 'tor grinding-g variouel subi'stances, other than food, have been inade which use the principle of a. convex rota-tine` surface operating against a stationary concave surface. I do not, therefore, elaiin such a combination broadly, but

I cla-iin:

Iii a food grinding device, the coinbination o'f a. traine consisting of two ineinhers having a hinged connection; a rotative `grinding' clement with a covering of Wire inesh constituting its vgrinding surface and having,v a shaft and handle attached thereto; means provided v["or mounting said grinding eleineiit on one oit said traine inemhere .in a plain hearing permittingl free and continuous; rotation el said eriiidiireelement; a Wire inesh receptacle, :uipported by the other of said :traine ineinhers, said Wire inesh receptacle to receive said grinding element and permit of 'free and continuous rotation oit' said grinding element therein, substantially as described.

Signed this 5th day of May, 1927.
